[Repeater-Builder] Band Pass Duplexer Tuning

[fxbuilder]

There is a great article on this site about tuning a notch duplexer by
Kevin.  Can similar methods be used for tuning a mobile 6 can band
pass duplexer?  Is there an article that I missed that explains it as
easily?  I need to re-tune and could use the help.  I think I know how
but thought I'd check.
